Quick Before They Catch Us was a 1966 British action/adventure children's television series. It starred then child actors Pamela Franklin, Teddy Green and David Griffin as three teenagers who become amateur detectives in Swinging London during the mid-1960s. Although the series was short-lived, all three stars went on to have long and successful television careers in both the United Kingdom and the United States. Its theme song, written and performed by Brian Epstein's Paddy, Klaus and Gibson, later became a popular tune and one of the group's first hits after releasing it as a single.

Plot

The series concerns the adventures of three London teenagers: Kate (Pamela Franklin), Johnny Martin (Teddy Green) and Mark Dennison (David Griffin), who use their unique talents to solve crimes in their neighbourhood. Kate, the youngest of the three, possessed a photographic memory and was a talented artist; as well as a sketch artist, she most often trailed suspects. Johnny was a technology student and often built surveillance equipment and other inventive gadgets. Mark (David Griffin) was the "nerdy" bookworm of the group, arguably the most intelligent of the three, and was the photographer.
